Ok,

Going back to the gps_position example from the manual, 
http://www.boost.org/libs/serialization/doc/tutorial.html#simplecase

If I change nothing other than what is below, then:

const gps_position* g_ptr = new gps_position(35, 59, 24.567f);
oa << g_ptr;

gives us:

cqc$ g++ -o test.o -c test.cpp
/usr/local/include/boost/archive/detail/oserializer.hpp: In function 
'void boost::archive::save(Archive&, T&) [with Archive = 
boost::archive::text_oarchive, T = const gps_position*]':
/usr/local/include/boost/archive/basic_text_oarchive.hpp:78:   
instantiated from 'void 
boost::archive::basic_text_oarchive<Archive>::save_override(T&, int) 
[with T = const gps_position*, Archive = boost::archive::text_oarchive]'
/usr/local/include/boost/archive/detail/interface_oarchive.hpp:85:   
instantiated from 'Archive& 
boost::archive::detail::interface_oarchive<Archive>::operator<<(T&) 
[with T = const gps_position*, Archive = boost::archive::text_oarchive]'
test.cpp:43:   instantiated from here
/usr/local/include/boost/archive/detail/oserializer.hpp:560: error: 
invalid application of 'sizeof' to incomplete type 
'boost::STATIC_ASSERTION_FAILURE<false>'

Also:

gps_position* g_ptr = new gps_position(35, 59, 24.567f);
oa << g_ptr;

and:

gps_position* g_ptr = new gps_position(35, 59, 24.567f);
oa << *g_ptr;

Both result in a STATIC_ASSERT failure, with T = gps_position*, and 
gps_position respectively.

The only case I can get to compile is:

const gps_position* g_ptr = new gps_position(35, 59, 24.567f);
oa << *g_ptr;

In my code zz_memory is just a plain base class, its tracking is not 
changed, I have done some project wide searches for the tracking macros 
and none exist, however the gps example is totaly fundamental and still 
won't compile.
